E250D

Overview

The SolaHD E250D is a 250 VA industrial control transformer with dual primary windings rated for 240 V and 480 V, providing a single 24 V secondary output. It features wire lead termination and bracket mount installation. The unit operates at 60 Hz within a temperature range of 0 C to +105 C. Physical dimensions are 5.36 in length, 4.5 in width, and 5.21 in height, with an approximate weight of 5 kg.

Feature Summary

• Epoxy encapsulation seals copper windings against moisture, dirt, and industrial contaminants
• Dual primary winding configuration supports flexible voltage input selection
• Bracket mount design facilitates secure panel or enclosure installation

Applications

• Industrial control panels requiring isolated power supply
• Machine tool electrical systems
• Automation equipment auxiliary circuits

Procurement Notes

Verify the specific secondary voltage requirement before ordering, as the E250 series includes variants with different outputs such as 120 V (e.g., E250WB). Confirm that the 24 V secondary specification matches the target load. Ensure the dual primary voltage rating aligns with available plant power distribution. Check RoHS compliance status if environmental regulations apply to the project scope.

Selection Notes

Select this model when a 250 VA capacity is sufficient for the control circuit load. The dual primary option allows compatibility with both 240 V and 480 V supply networks without rewiring. Consider the physical envelope size and bracket mounting style for integration into existing enclosures. Verify that the operating temperature range meets the environmental conditions of the installation site.

Part Context

The E250D belongs to the SolaHD SBE Series of encapsulated industrial control transformers. This line utilizes epoxy potting to enhance durability and protection against harsh industrial environments. The series offers various power ratings and voltage configurations to meet diverse control system requirements from Emerson Electric.

Replacement Considerations

Direct substitutes include other SolaHD models within the same SBE encapsulated series that match the 250 VA rating and 240x480V to 24VAC conversion ratio. Verify dimensional compatibility and terminal type equivalence before swapping components in existing assemblies.
